Filed: 1988-07-22
Abstract: A method for producing a composite hollow fiber membrane by coating a porous hollow fiber substrate with a dilute solution of a membrane-­forming composition containing a membrane-forming material and a solvent therefor by contacting the porous hollow fiber substrate with the composition, partially evaporating some of the solvent from the coated porous hollow fiber substrate, contacting the partially dried coating porous hollow fiber substrate with a coagulant and recovering the composite hollow fiber membrane. Also included are the composite hollow fiber membranes so produced and their use as permeable membranes for separating at least one fluid from at least one other fluid in a fluid mixture.

Abstract: The process of this invention is a hybrid gas separation process which recovers both heavy hydrocarbon and high purity hydrogen products from a gas stream containing a relatively low concentration of hydrogen. The heavy hydrocarbon product may consist of C 2  + , C 3  + and/or C 4  + hydrocarbons. The light hydrocarbons and other light components, such as N 2  and CO, are removed as a light fuel gas stream. After conventional removal of any components which might freeze at low temperatures, the feed gas is combined with recycle gas from the hydrogen purifier and fed to the cryogenic unit.

Abstract: A new manhole cover support and its processes of manufacture and use are shown. Such cover supports are used to raise the effective grade of the existing manhole cover as before road resurfacing. The cover supports are mounted upon an existing manhole cover receiving structure which has an upwardly-extending shoulder surface and a sill therebelow for accommodating such cover and the new cover support. The new cover support has an expansible body (1) with flexible, compres­sible retention component (16) for increasing its frictional grip to the shoulder surface. Advantageously, the retention component and any seals comprise a curable polymeric material. The receiving structure can be an existing manhole cover frame or previously-installed cover support. Some embodiments of the cover support can be adjusted as to elevation; the bodies of some are one piece and others are segmented into a plurality of connected segments. They can be sealed against substantial water infiltration.

Abstract: This invention relates to a wire cut electric spark machine (10) equipped with an electric shock prevention means. A guide roller (34a) which is disposed in front of a recovery box (38) for recovering an electrode wire (30) that has passed through an electrical discharge zone (36) and has been used up is mounted onto a substrate (56) made of an electrically conductive material and is fixed to a machine frame (26) through an insulating plate (58). A leakage current that leaks to the substrate due to disturbance in the travel of the electrode wire is caused to flow to a safety circuit (50) through a lead wire (52) and the leakage current signal stops instantaneously the supply of power of a discharge power source device (51) so as to prevent in advance an accident such as electric shock.

Abstract: L'appareil de positionnement décrit sert à positionner avec précision une pièce d'un dispositif par rapport à une autre et est destiné à être compatible avec des espaces sous-vide, de façon à pouvoir être utilisé dans des chambres sous ultravide. A cet effet, aucune lubrification n'est permise sur les pièces en mouvement les unes par rapport aux autres, de sorte que tous les contacts coulissants au niveau des surfaces en mouvement les unes par rapport aux autres doivent être évitées. Le mode de réalisation préféré est destiné à être utilisé pour faire tourner un réseau de diffraction à l'intérieur d'une source lumineuse monochromatique du type Cerny, Turner sous ultravide. Un organe de translation piézoélectrique linéaire de type INCHWORM (60) est utilisé à l'intérieur de la chambre à vide pour effectuer l'entraînement d'un élément de sortie (64) en paliers croissant à très petits pas avec une très grande précision. Une bande (61) est utilisée pour transformer le mouvement linéaire de l'élément de sortie en mouvement rotatif du support (53) du réseau de diffraction, ce qui est obtenu par enroulement de la bande autour d'un support cylindrique (58) du réseau de diffraction et par fixation des deux extrémités de la bande par l'intermédiaire d'un dispositif de tension (65) à l'élément de sortie (64), produisant ainsi une transmission du mouvement sans dérapage. Un pivot flexible (48, 49) est utilisé pour soutenir le support cylindrique à partir d'une structure fixe, de façon à permettre la rotation du support sans glissement ou sans jeu. Un détecteur, constitué par exemple par un lecteur à échelle optoélectronique (74), lit la position du support rotatif directement à d'une échelle de bande (73) enroulée autour dudit support, de façon à fournir une indication sur le mouvement du réseau.

Abstract: Fault current protection device, in which a first subordinate device, which acts as a fault-current circuit-breaker, for protecting against fault currents of a first type, is combined with a second subordinate device, which acts as a residual-current circuit-breaker, for protecting against fault currents of a second type.
